Sgs2 keeps switching itself off, 2-3 times per day??

Same pattern here, though it has not happened today, but I never got round to deleting any of the suspicious apps we mentioned in the previous post!!
go figure??

Thanks for the suggestion, but I'm afraid that that is not the case.
It almost never turns off after it has been used for a while, etc. I just sometimes unlock the phone, read a twitter reply or an email, lock it back and 5 minutes later its off.
Sometimes it switches off while in my pocket, sometimes - while laying on table. No clear pattern...

Ok. If you have changed from Gingerbread to ICS did you go into Recovery Mode and Clear data + Clear cache (and if ClockworkMod Recovery) + Clear Dalvik Cache.

I am having the same problem There seems to be a pattern that after taking it off charge for the night it works fine but an hour or so later I find it has switched off. I then need to remove the battery to turn it on again. It then works fine for hours. Another possible issue is that it some times happens a few minutes after I have removed it from the car dock. I have a suspicion it may have something to do with charging. I have two batteries - same problem with either battery - so not the battery. Is there any app out there that can track which apps were running at the time of the reboot ? That would maybe help to pinpoint the problem.

If you are rooted you can view your system dump files. Logcat should also record any issues with the system.

i had the issue with my galaxy switching off starting with gingerbread, but thankfully not too often, then when i updated the firmware to ICS it seemed to do it several times on some days, then not again for a few days etc etc. basically, i found that if i unticked the box that stopped apps from updating automatically, it stopped the issue of switching itself off. in fact, not done it once.

hope this helps somebody, cos it's a v frustrating prob

also, if you have an aftermarket case/cover, make sure it's not pressing on the battery as this can have an adverse effect too

I had this random powering off, sometime 2-3 times per week. I routinely tended to use my phone as normal during the day, and pop it on charge overnight as I went to bed. I realised that I was never fully discharging the battery was just doing what is referred to as a 'common' charge (where you charge the phone when the battery remaining is more than 20%). I think this was the source of my problems, the battery was never getting conditioned properly.

Once a week or so, I started doing a full charge (letting the battery drain down to below 20%, the lower the better) and THEN popping it on charge.

Since doing this, my random 'power offs' seem to have stopped.

I hope this helps some others with the same problem as it used to drive me crazy....
